its broader aspects this invention re:

chines isloper atedto perform certain fune tions, it; is locked orrendered inoperative at the end of' said operation, and is unlockedor're'ndered operative only upon the operation of theother device ormachine. Furthermore, this v interlocking dr connecting mechanism is'soconstructed that the first mentioned machine maybe repeatedly 0p--erated Without an intervening operation of the second machine or device.

In .the 'specific. embodiment of this. invent-ion the interlockingmechanism has been shown, as connecting a cash register or accountingmachine and a filing cabinetwhich are of forms well kno-wnon the market.

. When'the accounting machine is operated for. the purpose of enteringcharge or received on accoimt" transactions therein. the machineisautomaticallyflockaj, at the end of the operation and remains i tionuntil the filing cabinetis operated, which. operation willautomatically'release the accounting machine." In' the entering of cash,and jpaid out-transactions the above;mtionedlocking mechanism for theaccounthg-,.,i nachine is not broughtinto.

play; tli 'erelforepermitting successive operations of themachinewithout anintervening operation ofthe filing cabmet. In thespegifi-fie.embodiment of the invention, the ar- Xi'angeme-nt describedis very desirable. as

. two devices ormachines are in use, a clerk frequently ,in an 'establishment where the after making a chargei transaction or receiving cashon account. may make the proper. entries uponthe loose leaf system whichis in universal use and then deposit the leaf or slip in the filingcahinet without making the proper 'entry in the accounting machine.With-'the described inventionin said keys.

suc 1 condi -parts the e sential'elements of which are set forth in. tieappended claims-and a preferred form of embodiment of which is drawingswhich accompanyand form part of this specification. 1

Figure 1 is a'perspective view of the ac counting machine and filingcabinet used in the specific embodiment of this invention. Fig. 2 is -"aside elevation of the invention, showing the filing cabinet .or slipreceptacle partly in section. Fig. 3 is a.transverse sectional viewthrough the accounting machine, showing the special counters and a partof the interlocking mechanism. Fig. 4 is a detail view of the specialtransaction keys and bell crank levers for operating the specialcounters which are positioned by Fig. 5 is a front elevation of the bellcrank levers shown in Fig; 4'and mechanisin coiiperating therewithlFig.- 6 is a 'earelevation of thepart of the interlocking mechanismwhich is locatedin the accounting machine.

The cash register shown in the drawings is of the type shown anddescribed in the patent granted to Cleal and Reinhart April'-hereinafter shown with reference to the.

as shown comprises three banks of amount' kevs 1 and an additionalbank-which isprovided with clerks initial keys 2 and special transactionkeys 3. As shown in this patcut the amount keys control differentialmechanismwhich in turn actuates the totalizmg, indicating and printingmechanisms,

while the clerks kevs'and the special trans-- action kevscontrol1devices for indicating and printing only. Power is applied to"the machine b v a crank handle 4, which through suitable. interveninggearing, not shown, rotates a shaft 5 (Fig. 3) through a completerotation'upon each operation of the machine.' This shaft 5 is connectedto a shaft 6 b v arms 7 and 8-and a link 9. 'Upon each ios to an extentofabout 90, and then back to its normal position.

The special keys 3 provided with key pins 10 which playin elongatedslots '11 formed in horizontal arms 12 of bell crank levers 13, whichlevers are shafts 21, the latter being suitably mounted in an auxiliaryframe 16. --A plate 22 is attached to the auxiliary frame 16 and passes20 provided with apertures 23 through which over the counter wheels20.This plate is the numbers on the counter wheels may be read. At theextreme lower ends of the downwardly extending arms of the bell cranklevers13slots-24 are provided. Whenever one of the special keys isdepressed the lever 13 coiiperating therewith will'be rocked inananti-clockwise directionso that the slot 24 formed in the lower end ofsaid lever will pass around a pin 25 extending laterally from theforward end of the horizontal arm of .a bell crank lever 26, which ispivoted upon a rod 27- suitably mounted in the frames 17 of the machine.i

Upon the rotation of the-shaft 5, a pin 28, projecting from an. arm 29secured to the rock shaft (i and into a cam slot 30 formed in theupper'end of the .vertical arm of the lever "26, will rock this lever inan anticlockwise direction, by which movement the pin 25 carried by thelever will lower the lever 13 of the operated key. By this movement thelever 1-1, to which the operated lever 13 is connected, will be rockedabout its pivot 15 thereby actuating the units wheels of the specialcounter corresponding to the operated key. By this operation it will beseen that upon the operation of any one of the special keys 3,.one unitwill be counter, so that a correct account .will be tept of the number'of the different special transactions entered in the machine, Thiscounter constructionis well known in the art, and no furtherdescriptionof it need be given.

The filing-cabinet or slip receptacle, as shown in Figs. 1 and 2,comprises a ,plurality of trays 31, which are pivoted to' a plate32secured to a false back 33 of the cabinet. The trays 31 are arranged insections and each tray of the various sectionsrests'upon the trayimmediately below it so that when any one of the trays is elevated byits projecting fiange34 all of the trays above it will be elevated orrocked about (Figs. 3 ands) arev.

\their pivots. I Each trayis provided with a of each section is a plate36 which normally closes the space above the upper tray of each section.Each of these plates at. its

-lower end is provided with a bail 37, the

free ends of which are secured in the partitions 38 of the filingcabinet and thereby act as a pivot for said plate.

Plates 39, only one of which is shown, are secured to the partitions 38of the .filing cabinet and these plates are provided with cam slots 10into which project ,the ends of a rod 41 which extends through flanges-12 of each of the face plates 36. The lower end of this face plate .36rests upon the uppertray 31 so that when any one of the trays is liftedthis face plate will also be lifted.

kno\vn forms, and haye been placed upon the market in large quantities,and it is thought that from the abovedescription the operation of bothof these devices will l".- generally understood. The liling cabinctis ofthe type shown and described, in an application of lvilliam H. Muzzy.filed October 18, 1906, Serial No. 339,539, and for a furtherdescriptionthereof reference may be had to said application, though thedescription just given is sutlicient for an understanding of the presentinvention. 7 Viith this general description of the operation of thedifferent devices, the description of the connecting or interlockingmechanism between said de .1 ces will be next taken up. Thisconnectingor interlocking mechanism between the accounting machine and the filingcabinet is of such construction, that when certain transactions areentered in, or certain functions performed by -the accounting machine,it becomes necessary to operate the filing cabinet before a subsequentoperation-can vbe made on the accountin machine.

upported bv the flanges 42, of the face plate 36 (see Fig. 2) of eachtray section of the'filingcabinet, is a rod 43 with which the forwardend of a lever 44 contacts. This there is one of these arms 44 for eachsection The shape of the cam grooves #10 of the of the filing cabinet,andthat the said cabinetmay be of as many sections as desired.ProJecting forwardly from and fast on one end of the shaft 45 is an arm46.to the forward end of whichis connected a downwardly extending link47, whichat itslower end is connected to a transverse shaft 48 by an arm49. I This shaft 48 extends through a base plate 50 uponwhich both thefiling.

cabinet andthe accounting machine are mounted. Extending rearwardly fromthe shaft 18 is an arm 51 (see-Figs 2 and3) .tothe rear end of which issecured the lower end o'f a slide 52 the upper end of said slide beingprovided with anelongated t.

ii r3, through which extends aiscrew 51 pl 0- ectmg from a plate' 55,which is fastened to a tie bar 56 located in the rear *ofjthe accounting machine. .A t; the re'ar edge of the slide 52 a'ndgnear itsupper end is a notch 57, in which normally rests a pin 58- projectingfrom the rear e nd of a s lide 59. This slide 59 at its rear end is alsoprovided with Jan elongated slot 60, throughwhich the screw 54: extendsandat its forward end the said'jslideis connectedtoa bell crank lever61, whichis pivoted upon a rod 620 suitably secured in the machineframes 17. The hori zontal.arm of thelever 61 is located immediatelybelow and 'in the path of the downward movement ofthe bell'crank levers13 which cotiperatefsee Fig. with the received on account? and chargespecial keys 3; these keys being the second andv third from the bottomof the special bank of keys.

It is to benoted. that in the normal posi- I tions of the parts. asshown in Fig. 3, no

' withthe slip receptacle maybe opened. This follows from the fact thatthe opening of anyreceptacle compels an elevation of arms 1- andconsequent depression of-shde 52. However,

slide 52 is locked in elevated position nor-. mally by the engagement ofpin 58 on slide 591with the upper edge of. notch 57 in slide 52. Towithdraw pin 58 requires an opera tign of either the received on accountor the charge key of the accounting'machine. It will be recalled thatupon the depres sion of any one of the spacial keys 3 and theoperation'of the crank handle 4 of the accounting "achine, the leyer 13,cooperating -pressedspecial key, will'be lowered by rocked in ananti-clockwise direction, which movement will carry the slide 59 rear-'wardly, so that the pin 58 projecting from the rear end of'saidslide-will pass "from under the shoulder formed .by the notch 57" in therear edge of theslide The lower I edge ofthe slide'fi is'pi'ovid'ed witha notch" 62' into. which'a plunger63' is forcedby a spring-64 (see Figs.3 and 6) when the'slide shaft 45 the slide 52.

'been moved-downward to an extent sufficient .e pin of'the bell crank26. Upon t-ht owering of the lever13 cotiperating with ther the received,on account or' charge xey, the lev er 61 will therefore be 59reachesitsrearmost )ositiom This plunger 63 is guided by I anges .65extending from the plate 5.5. Y

\Vhen the slide 59 is latched in its rearmostposition by the plunger 63,the shafts and 18 arefree to be rocked by the rods 43 carried by theface'plates 36 of the dif-' ferent tray sections against the'tension ofa coil spring. 6 6'upon the exposure of any of the trays or slip.receptacles. The ends of the spring 66 are securedto. the arm 46 andbyj-the rearward movement of tlie slide' 59.,.

in which position of thelever,"the shaft 5 will be preventedfro'm'rotat'ing until the lever 6.9 isretu'rned to its normal position,as shown 'in F 1g. 3, which movement is accomplished upon the eirposingand concealing of one of the receptacletrays.

As previously. described the face plates 36 have a. slight upwardmovement when any one of the trays of that section is elevated, which;upward movement will through rod 43 elevate the forward'end of itscompanion arm 44, thereby rocking thein a ,clockwise direction andthrough the arms 46 and-49 and the link l7 rock the shaft 4-8. in asimilar direction.

This movement of the shaft 48 will draw the slide 52 downwardly and nearthe end of its downward movement the upper end of a slot 73 formed insaid slide will contactwith a pin 71 projecting from the plunger 63 andmove said plunger out of the notch 62 in the slide 59. .Tlie slide 59will bep'revented from returning to normal positionby the contact of pin58, which pro jects from said slide. with the rear edge of When,however. slide 5'2 has to withdraw theplunger 63 from the notch 62 theslide 59 will move forward slightly under the action of spring so as tocause the rear wall of the notch -62-to pass above the plunger 63 thusto preventfthe plunger again entering the notch l when'the slideis"restoredjasfollows. \Vhen the trays are 'i'eturnedlto their normalconcealing positions the-shafts 45 and 48 will be rocked 1n ananticlockwise"direction lay-,the spring 66 "by which movementthe slide willbe fully. elevatedfithereby presenting the recess 57 to the 1pin 58 oftheslide 59 and' rm tting the utter to be fully returne to its norinalposition, as shown in Fig. 3, this return being caused by a. spring 75having its ends connected to the lever 69 and to the machine .frame.

Bearing against the ends of the rod 41 carried by the flanges 42 of eachface plate 36 (see Fig. 2) are-arms 76,"only. one of which is shown, andwhich arep voted to thepartitions 38' at the'same point as the bails 37,whichare. also connected to the face plates 36. v Each of: the arms" 76'has gain access to thetrays of the filin cabinet without first deressing either the charge or receivedp n saccount keys and thenoperating the accounting machine, after which it'is impossible again tooperate the machine until the filing cabinet is operated. It-isalso-evident that the locking mechanism.does not come into operation"when either a 'cash or a paid out transaction -is 'entered in themachine and consequently transactions of either of these classesmay berepeatedly entered in the machine without an". inte" veni'ng' operationof the slip re ce'ptacle of filing cabinet.

VVhile this connecting .or interlocking f me chanismwhas been shown forthe purpose of requiring a certain sequence of operations between-anaccounting machine and a credit cabinet: when certain transactions areen- -teredzfin the machine, it is not intended to limit: the use of thisinterlocking mechanism chines. 1
